I recommend that if each musical is sent for free, then the company's reputation will grow further for those who are interested in learning the musical instruments in the future and everyone will benefit and Rubusel will get the company and profit dividend. Thank you.

While playing a song, there could be a button that would save the current point,ie in the middle of the song, and when you choose "replay song", it will start from the middle. Otherwise, it could create a new midi song which it would start from the middle until the end,or until a point you may choose. It would be like the "repeat" the video players have, which you set the A and B point and this makes the video play the selected partition play again and again.
